Summary

Description

This tile cache service shows the locations of both in service and out of service submarine telecommunication cables from the North American Submarine Cable Association (NASCA) in coastal and offshore waters within the Exclusive Economic Zone (EEZ). Submarine cable data were originally received from NASCA as Route Position Lists (RPLs), and geospatial products were later received from Pacific Marine Systems, which had contracted with NASCA to produce datasets using the same RPLs. The geospatial data from Pacific Marine Systems were compared against the RPLs and subsequently used in tile cache creation. Submarine cable locations were screened out within 100 meters of landfall, in addition to cable segments that extend beyond the EEZ and do not reenter U.S. maritime waters. Cables which exit and reenter U.S. waters remained intact. Cables are visible from a scale range of 1:18,489,298 to 1:36,112. Each cable contains annotation which references cable name, segment (if applicable), and ownership. Annotation is available at scales from 1:577,791 to 1:72,224. Visual representation of cables and annotation used published NASCA charts on NASCA's website (http://www.n-a-s-c-a.org/cable-maps) as a guide.
